I just has a WD mybook (hooked to my airport express) fail to read and making weird sounds. I'm pretty sure the drive is dead. I am planning to move another WD drive I have over to the airport express, and purchase another to replace it. I was looking at both FireWire and USB types. Any suggestions? Another topic is that I want to convert my Bluray to 1080p apple tv 3 files. I need to pick up a Bluray drive (reader or reader/writer). Any suggestions for that device? FireWire or USB? If it matters, I have a 2011 iMac I am goIng to encode with.
